| Research Abstract |
Hepatocellular carcinomas could not be classified according to their phenotypic expression, since there were diverse patterns. In contrast, in intrahepatic cholangiocarcinomas, Notch2 was expressed in 56% of cases. Although Notch2 expression was inversely correlated with CD44 expression, this expression was significantly associated with c-Kit expression, suggesting that intrahepatic cholangiocarcinoma with positive Notch2 expression might be derived from hepatic progenitor cells. Survival among patients with positive Notch2 expression was significantly better than that among patients with negative Notch2 expression, indicating that Notch2 expression might have a connection with clinical behavior of intrahepatic cholangiocarcinomas. The expressions of MUC1 and MUC2, as well as p53, in intraductal papillary neoplasms of the bile duct were found to be different from those in conventional intrahepatic cholangiocarcinomas.
